An ECU (Engine Control Unit) may continue running after the engine is shut off due to a few reasons. One common cause is a faulty ignition switch that fails to completely disconnect power to the ECU. Additionally, if there are issues with the wiring or relays that control power to the ECU, it could remain active. Lastly, certain systems, like those for diagnostics or emissions monitoring, may keep the ECU engaged for a short period post-engine shutdown.

Why does your Car Keep Running?
If you mean the engine continues to run after you shut it off, then it's called dieseling. It's caused by carbon buildup on the tops of the pistons, which can get red hot (called hot spots). Sometimes after the engine has been shut off, fuel injectors or carburetors leak gasoline into the cylinder and onto the hot spots, which ignites the fuel and can cause the engine to continue to run. Try running a fuel system cleaner to get rid of the carbon. If that doesn't work take the car to a garage and have them test the injectors.
